On an impulse yesterday I bought two gorgeous blue delph plants for $7 each. Gallon size, healthy, full, several stalks in bud and some in bloom. Now I'm scared. I kill delphiniums every time I plant them. I don't have a proper place, proper soil, light, aaaaccckk!
Any tips? What can or should I do to amend soil to give them a better chance? Is August really a good time to even plant this perennial?
